Description: Node Health Check is a critical process in managing server clusters, allowing for the assessment of the operational status of a specific node within a distributed system. This process involves evaluating various parameters such as availability, performance, and responsiveness of the node. In distributed environments, health checks are essential to ensure that nodes are functioning correctly and can handle assigned workloads. The checks are performed by executing tests and queries that determine if the node is active and can communicate with other nodes in the cluster. Additionally, this process helps identify potential issues before they escalate into critical failures, enabling administrators to take proactive measures to maintain system stability and efficiency. Node health checks not only focus on failure detection but also provide valuable insights into the overall performance of the cluster, allowing for optimization of configuration and resource allocation. In summary, Node Health Check is a fundamental practice to ensure the operability and performance of distributed systems, contributing to the resilience and efficiency of the applications that depend on them.
